Two people are dead after a single-vehicle collision on Highway 401 early Wednesday morning.
Toronto EMS were called to the scene at around 4 a.m.
Emergency crews arrived to find a single vehicle wrapped around a pole between the eastbound express and collectors lanes near Warden Avenue.
Paramedics said two people were pronounced dead on scene.
Ontario Provincial Police Sgt. Kerry Schmidt tweeted that the investigation is ongoing but that speed may have been a factor in the crash.

Police are also looking into road and weather conditions as possible factors.
OPP Const. Prash Niranjan said officers are working to identify the deceased but have not yet been able to get into the vehicle.
He said officers will detach the vehicle from the pole and decide whether to remove the occupants at the scene or send everything to the Centre of Forensic Sciences in Toronto.
The eastbound collectors lanes between Warden Avenue and Kennedy Road were closed for several hours but OPP have since reopened the center and right lanes.
The eastbound express lanes were also closed from Leslie to Brimley Road, but were reopened just after 11:30 a.m.
Police are hoping to have all lanes reopened by noon.
Niranjan said police need to ensure the pole is structurally sound before allowing motorists back in the area.
